After Effects Tutorial: Parametric Particles

Pretty cool tutorial showing how to make a helix path using some expressions that represent parametric equations. Here's the expression i used: for x,y: t=time; [400*Math.cos(t),400*Math.sin(t)] for z: 50*time; Try messing around with the values. What happens when you change the 50 to 100? What about for x and y, change one of the sin or cos to 2t on the inside?
